Fuel Efficiency Test NP300

We tried to figure out what impact a hardtop has on a car.

We did this by testing some various aspects on a car with a hardtop and a car without a hardtop, in this case a Nissan NP300. The tests show us that the impact of a hardtop on a car is not negative. By investigation of the sound waves, we can even notice that the louder sounds are displayed behind the hardtop, so further away from the cabin. In all the other aspects, both test vehicles had the same results. We also notice that the friction in the corners of the trunk has been reduced thanks to the hardtop.
